BUILDING BLOCK OR BRICK.

Application filed June 5, 1924. Serial No. 718,095.

To all whom it may concern:

Be it known that I, CHARLES J. R-EBMANN, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Building Blocks or Bricks, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to building blocks or bricks and has for an important object thereof the provision of a block or brick which in a complete wall structure provides at opposite sides of the wall oppositely directed ventilating surfaces.

A further object of the invention is to provide abrick of this character in which each brick is of the depth of the wall to be constructed and in which the brick itself is so constructed that the layers of mortar securing opposite sides of the brick in position in the wall are bonded through the brick, thereby insuring a permanent structure.

A still further object of the invention is to provide a device of this character which may be very cheaply and readily produced andwhich employs in its construction less clay than is ordinarily necessary in the constuction of the three ordinary building bricks which it replaces.

These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a perspective of a section of wall formed of blocks constructed in ac cordance with my invention;

Figure 2 is a front elevation of the wall partially in section, the section being taken through a bonding opening of the blocks;

Figure 3 is a perspective of one of the blocks removed;

Figure 4 is a further section through the wall taken through the vertical ventilation openings of the blocks.

Referring now more particularly to the drawings, the brick consists of a fiat rectangular slab 10 having one end face 11 and the adjacent edges of the two side faces 12 glazed. Adjacent this end wall the slab has formed therethrough a vertical opening 13. Adjacent its opposite end the slab has formed therethrough a horizontally extending opening 14:. Intermediate these openings a second vertically extending opening 15. is formed the purpose of which will presently appear.

In employing these slabs the slabs are preferably placed in the wall staggered jointed as is usual in the construction of brick and slab walls, mortar being laid between adjacent courses. In this construction mortar is also forced through the opening 15 until it combines with the mortar on the upper face of the course next below and connects the mortar of this course with the mortar on the upper face of the course just laic This mortar filling the interior of the brick or more particularly the opening 15 thereof provides a solid surface for approximately two-thirds of the length of the brick which is preferablymade of a depth equal to the thickness of the wall to be constructed or in ordinary walls about thirteen inches. Since the length of the face of the brick is made the size of the longest measure ment of an ordinary building brick, such bricks may be employed, as at 16, in filling in corners and about framing and the like. It is pointed out that due to the construction employed and, as more particularly shown in Figure 4, a continuous vertical ventilating space is provided at the outer face of the wall permitting any moisture which may seep through the outer face of the bricks to pass downwardly to the foundation 17 of the wall so that the wall will not be moist. At the same time in each course a horizontal ventilating space is formed by the combination of the openings 14 of the bricks, providing for heat insulation and rendering a building constructed in this manner cooler in summer and warmer in winter. The construction of the openings 13, 14 and 15 being capable of modification, no particular claim is made to the form of openings provided.

While I have above referred to the use of ordinary brick in the corner construction, I have not illustrated the same and in fact prefer that the filling at corners be accomplished by breaking a block 10 to provide this section. To this end the margin of the central opening 15 disposed next adjacent the glazed wall 11 is spaced from this glazed wall a distance equal to the width of an ordinary brick or slightly less than onehalf of the length of the entire block 10. It will be seen that by breaking the brick at the edge of this opening a guide is provided,

indicating the proper at the same time the weakened at this point pern' much more cleanly and evenl ordinarily be accomplished.

broken section I have herei A building brick rectangular slab liavin face a vertical openin adjacent the opposite e opening theretbrough a comprising point of breakage and openings a second vertical opening, the end fact that the brick is face adjacent the first named vertical openhis breakage ing and the adjacent portions of the side y than could faces of the slab being glazed, the side of The use of this the second named vertical opening paralleln illustrated. ing the glazed end face of the slab, the end Walls of said second vertical opening being a flat separated from the side walls by thin, readadjacent one end ily breakable Walls.
